Answer: Well, Mike, no, you do not want to use Vaseline on your o-rings. The petroleum-based jelly eats away the rubber, causing the rubber to stretch, or tear sooner than normal. The preferred pool o-ring lube is a Teflon or Silicone base to keep the rubber soft and supple. Why silicone lubricant grease is the best type for rubber o-rings and seals. Most O-rings are made from synthetic rubbers. Namely: nitrile, EPDM and Neoprene. It is true that petroleum products will degrade natural rubber. Petroleum jelly on a rubber condom can cause it to break. I would think that it will also cause your moulding to deteriorate. Petroleum jelly on a rubber condom can cause it to break. Do not use WD-40 on o-rings. Just for everyone's information, WD-40 is NOT a lubricant. The WD is short for Water Displacement. It is used to remove moisture, loosen rusted parts, protects against rust and corrosion, and it CLEANS most surfaces. Lubricants are commonly used on O-rings and other elastomeric seals. Using a grease or an oil at assembly helps protect the O-ring from damage by abrasion, pinching, or cutting. It helps protect some polymers from degradation by atmosphere, and its presence helps extend the service life of the O-ring.

Vaseline and any oil base grease will break down the Nitrile Butadiene Rubber in 6 months to a year. Oils, like olive oil or WD40 or 3-in-1 oils are too thin and will not stay in place for long at all. There is NO suitable substitute for Silicone Grease.

Re: Lithium Grease and O-rings It's a silicone grease with teflon in it. The grease is slick and harmless to o-rings and the teflon matters where there's metal to metal contact (the threads of our lights).

WD-40 thick High-Performance White Lithium Grease lubricant provides great protection for heavy duty, metal-to-metal applications. It can be used outdoors regardless of weather and temperature conditions. This makes it ideal for use on automotive connections, tow bars, gear and brake mechanisms and CV joints.

any - white lithium grease good on rubber. Silicone grease is safe on rubber and actually helps to keep it soft. Any other grease with a mineral oil base will degrade natural rubber.

WD-40 isn't actually a true lubricant. WD stands for "water displacing" and its main use is as a solvent or rust dissolver. The lubricant-like properties of WD-40 come not from the substance itself, but from dissolving components. WD-40 can be a good substance to start with — it can help clean up rust or other grime.

According to the website WD40 is safe on rubber. The only materials which are mentioned as being affected are polycarbonate and clear polystyrene.

The most common causes of O-Ring failures include: Improper gland design, allowing for too much or too little compression, not enough for seal expansion and tolerance stack-up. Incorrect O-Ring size. Incompatibility of O-Ring elastomer and environmental elements.

you should use 100% silicone grease. For a regular MPI injector, Vaseline works great. Use on both the top and bottom. That is what I use for all my O-rings.

WD-40 doesn't really lubricate much of anything. It's actually a de-greaser, so it will remove any lubricant from bicycle chains, cables and other pivot joints. If you're cleaning your chain for re-lubrication purposes with a product other than WD-40, then WD-40 will be fine to use.

Can I use WD40 to clean all of the holes in my carb and my float bowl? Yes you can use wd 40 but its effectiveness will only be as good as its presurissed value, and may as well use one of those compressed air can computer air blowers.

It can be used to lubricate fountain pen filling mechanisms and threads. It is used to seal and preserve O-rings in flashlights, plumbing, waterproof watches, and air rifles. Silicone grease is widely used to lubricate threads of water-submersible flashlights used for diving and spearfishing.

WD-40 can swell rubber or buna rubber gaskets when the gasket is immersed in the fluid. If the fluid is sprayed on and wiped off, the gasket will not swell. This swelling will not ruin the gasket, however it will swell the rubber.

A light oil is typically best for your bicycle chain in average to dry riding conditions. Light oils are good at penetrating the bushings of chains to minimize the amount of wear that occurs between the links.
